Note which color wire is coming out of each pickup.

Gently flip over your guitar and put it on a soft towel or other soft material. Take off the control cavity cover.

Desolder the wires of the pickup from the terminal that is touching the back of the potentiometer, or pot.

A potentiometer is what the pickups are wired to that allow the player to have on-board control of their volume and tone. Terminals are the parts on a potentiometer that you solder the wires to.
